0
FAST_EVENT_CLR_REQ
0x50
Event or error bit/s clear request
1
Reg
0x45 – 0x48
0x4B – 0x4C
Event or Error register to be written
2
mask
Mask to apply to the specified register
(e.g. 0x01 clear bit 1 of the specified
register)
BYTE
FIELD

DESCRIPTION
0
FAST_DISABLE_INT_REQ
0x51
Event or error interrupt/s disable request
1
Reg
0x41 – 0x44
0x49 – 0x4A
Event and Error enable interrupt register
to be written
2
mask
Mask to apply to the specified register
(e.g. 0x01 clear bit 1 of the specified
register)
BYTE
FIELD

DESCRIPTION
0
FAST_ENABLE_INT_REQ
0x52
Event or error interrupt/s enable request
1
Reg
0x41 – 0x44
0x49 – 0x4A
Event and Error enable interrupt register
to be written
2
Mask
Mask to apply to the specified register
(e.g. 0x01 set bit 1 of the specified
register)
BYTE
FIELD
VALUE
DESCRIPTION
0
FAST_EXTRACT_REQ
0x53
Fast Extract Request header
1
Location
0x00 – location 0
0x01 – location 1
Since DSP can extract two services
simultaneously, XM stack assigns an
extraction location.
2
channel_or_sid_flag
0x00 – use channel number
given in byte 3.
0x01 – use SID given in byte 4
If channel number is used, then the SDEC
will get the SID and PCIDs from CRW.
